Description

  The present invention relates to an image display device including an image display panel.

  Conventionally, most image display apparatuses of this type are designed on the assumption that they are installed indoors (see, for example, Patent Document 1). No measures were taken to protect it. For this reason, it has been difficult to permanently install a conventional image display device outdoors.

  In recent years, it has been desired that an image display device including a flat image display panel be permanently installed outdoors. The reason is that the image display device has a small thickness. When the thickness dimension is small, the image display device can be installed in a narrow place.

  In order to allow the image display device to be installed outdoors, it is conceivable to form a storage chamber having a sealed structure inside the housing and store the image display panel in the storage chamber. In order to make it possible to install the image display device on the ground or floor, it is conceivable that the casing is supported by a metal support. Here, the metal support base can be manufactured by connecting a plurality of constituent members constituting the support base by welding.

  In the support base that supports the housing, high strength is required at the welded portion between the constituent members constituting the support base. However, a high welding technique is required to increase the strength of the welded portion between the constituent members. Moreover, in the welding location, a part of component member melt | dissolves and the surface of a component member protrudes. When the surface of the support base needs to be smooth, the raised portion is scraped off, but this may reduce the strength of the welded portion.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an image display device including a support base having high strength despite its simple production.

  An image display device according to the present invention includes an image display panel, a housing that houses the image display panel, and a support that supports the housing, and the screen of the image display panel is externally provided on the housing.

The first component member and the second component member are connected in a substantially L shape by a connector. The connecting tool includes a contact member that contacts both back surfaces of the first component member and the second component member to be connected, and a first member member that contacts the corresponding contact member and is screwed into the contact member. 1 screw member and the 2nd screw member which penetrates the 2nd structural member which contact | abuts to a contact member concerned, and is screwed in a contact member are comprised. The casing is attached to the pair of first component members and / or second component members.

  In the said image display apparatus, each 1st structural member and 2nd structural member which comprise a support stand can be easily connected to a substantially L shape with a connection tool. In addition, despite the simple connection between the constituent members, a high strength can be obtained at the connection location. Therefore, even when the housing is attached to the support base, the connection between the first component member and the second component member is not easily broken.

In the specific configuration of the image display device, each of the pair of first and second components is a metal plate formed in a U-shaped cross section.
